I just won 200 rounds at auction. Most is ‘83 but some are dated 1992. I was hoping someone has experience shooting this date ammo and care provide feedback as to performance/comparison with the older stuff?

Also, I still have two bricks of ‘79 dated GP11 with the wax ring. I’m holding onto this for some reason. Was wondering if others are considering this to be better quality than the UN-wax ringed ammo? Is it considered of a higher collectible value than the others?
